While there were some good things about the v1 implementation of pie

I actually puzzled over this a bit when I first realised that Second
Life's pie menus worked this way. Originally, the pie menus worked
well when you didn't click too close to the edge of the screen but
didn't actually open under the mouse cursor if you did. Since the
"More..." item is sensibly always the southmost one, opening new
submenus centered on the mouse would cause the pie menu to drift down
the screen until it hit the bottom and caused problems.
Also, opening the submenu at the same location has the nice
side-effect that the mouse remains over the "More..." option for the
pie menus that are nested 3 or more levels deep.
What I have been contemplating is how to make it possible to open the
next layer of a pie menu without moving the mouse at all. Sadly, it'd
probably break too much from normal UI conventions to be worth doing.
If I understood him correctly, what Q seemed to think was the right
behavior is:
* The first mouse-down opens the pie centered on the mouse location,
so no choice is under the mouse
* If the choice is a submenu, each new menu is also centered on the
mouse
that way, you are never making a choice within the submenu if you
accidentally double click, because the center is never a choice. this
does mean that the nested menus 'creep', but that has the effect that
each nested choice is a 'gesture-like' unique series of clicks.
